    I wouldn't normally pester you mathematicians with something as trivial as this, but in my homework, I've come across a sequence impossible to answer by me.

    "What is nth term of the following sequence--1, 101, 1001, 10001, 10001. Write down the next two terms of sequence"

    The next two terms are 1000001 and 10000001, but the sequence is neither linear nor quadratic and those are the only types of sequence covered in Edexcel specification.

    Please help me :confused:

     101 = 10^2 + 1
     1001 = 10^3 + 1
     10001 = 10^4 + 1

    I don't know what it is called. I might call it a pseudo-geometric sequence, a power sequence or perhaps pseudo-exponential seqeunce... But you're not being asked to name this sequence anyway, surely?
